It’s More Energy Efficient.
We’ve mentioned this above – but it’s so good we have to again!

Using Open Cell Spray Foam insulation is one of the best ways to improve energy efficiency and thermal comfort. As a complete insulation and air barrier, it minimises air leakage which allows for the correct sizing of heating and cooling equipment. This provides dramatic savings on the initial cost of such equipment and ongoing utility costs.

The Open Cell Spray Foam Advantage

Open Cell Spray Foam helps create a barrier system in wall cavities and can fill an existing cavity wall or block wall assembly. This particular method allows an existing cavity wall to be insulated without the removal of the internal parts of the walls, providing a barrier of air at the same time as providing insulation of the wall with minimal impact to the wall cavity.

The advantage of this is reducing labour, time and the expenses of removing and replacing the existing interior face of the wall. In block wall assemblies Open Cell Spray Foam may be used to fill the interior cavities of the block to supply insulation and vastly reduce the air leakag, thus reducing the heat transfer of the assembly.
